Baby bump: The happy couple announced their pregnancy in July after Izzy (seen here on holiday in Antigua this week) suffered a heartbreaking miscarriage in 2014 and underwent ertility treatment

The happy couple announced their pregnancy in July after suffering a heartbreaking miscarriage in 2014 and undergoing fertility treatment.

At the time of the announcement, Izzy, who was diagnosed with polycystic ovaries in her twenties, said it was 'impossible' to answer people when they asked if she wanted to have children, as it felt like her heart was breaking every time.

Speaking to Hello! magazine, Harry said: 'You feel like you are never going to be the ones who get to say, "We are having a baby." That is why we feel so blessed now.

'In an ideal world when you're ready to start a family you hope you will conceive in the first few months of trying.

'We were like, no, no we won't need IVF, it won't be us. IVF was like something you didn't talk about. We thought it would be fine.'

Speaking of her happiness, mum-to-be Izzy said: 'Every baby is a miracle but we do feel so very lucky.

'I never wanted to stop believing that we would have a family. But you do feel like someone has pressed pause on your life and you can't go anywhere.'
